Nibbāna (Sanskrit: Nirvana) is the ultimate goal of the Buddhist path. It is the cessation of suffering (dukkha) and the release from the cycle of birth, aging, and death (saṃsāra).
The word literally means "blowing out" or "extinguishing," similar to how a flame is extinguished when it runs out of fuel.
Nibbāna is not the extinction of a "self" or a soul, because in Buddhist teaching, there is no permanent self to begin with. Rather, it is the extinguishing of the three "fires" that keep the cycle of suffering burning:
Greed (Lobha): Craving, attachment, and burning desire for sensory pleasure or existence.
Hate (Dosa): Aversion, anger, and ill-will.
Delusion (Moha): Ignorance of the true nature of reality (not seeing the Four Noble Truths).
When these three roots are completely uprooted, the mind is liberated.
The Pali Canon describes Nibbāna in two distinct phases:
This refers to the state of an enlightened being (an Arahant) who is still alive. The mind is completely free from defilements, and they experience unshakable peace and happiness. However, the "residue" of the five aggregates (the physical body and mental functions) remains. They still experience physical pain and pleasant sensations, but the mind remains untouched and unafflicted by them.
Often called Parinibbāna (Final Nibbāna), this occurs at the death of an Arahant. The physical body breaks up, and the five aggregates cease. Unlike an unenlightened being, there is no fuel (craving) to spark a new birth. It is the complete end of the round of existence, often described not as a place, but as the "Unconditioned."
Because Nibbāna is difficult to describe with conventional language (which deals with conditioned things), the Buddha often used metaphors or synonyms to point toward it:
The Deathless (Amata): Because it is free from birth, it is free from death.
The Unconditioned (Asankhata): It is not created by causes and conditions; it is the only reality that is permanent.
The Island: A refuge from the flood of suffering.
The Cool: The cooling of the burning fires of passion.
Peace (Santi): The ultimate tranquility.
It is not annihilation: Nibbāna is not a state of "nothingness" or the destruction of a being. It is the destruction of greed, hate, and delusion.
It is not a heaven: Heavens in Buddhism are temporary states of existence. Nibbāna is the exit from all temporary states.
It is not postponed death: One does not have to die to experience Nibbāna. It can be realized here and now in this very life.
Nibbāna is the highest happiness (Paramam sukham). It is the complete freedom from all bonds and the realization of the unconditioned reality. It is the destination for which the Noble Eightfold Path serves as the map and vehicle.
